[Is endovenous thrombolysis safety and efficacy in ischemic stroke comparable between patients aged over and above 80 years? Experience from an Argentinean cohort].

Introduction: Enrollment of patients aged above 80 years in trials assessing endovenous thrombolysis (rt-PA) was scarce. The goal of this study is to compare safety and efficacy of endovenous rt-PA between patients aged above 80 and those below 80 years.

Patients And Methods: A cohort of patients who received rt-PA was prospectively followed.

[Prevalence of silent cerebrovascular lesions in patients with obstructive sleep apnea syndrome].

Aim: To assess the prevalence of silent brain lesions in patients with OSA.
